Del Potro has won 11 straight matches in D.C.
Drawing ever closer to the bright lights of Flushing Meadows, the 2013 ATP Citi Open continues in Washington, D.C.
With the quarterfinals on tap for Friday, here are a few things to watch for throughout the day.
Can Juan Martin del Potro Continue Hard-Court Dominance?
Juan Martin del Potro has been nothing short of spectacular over the years in Washington, D.C.
As a result of two stellar victories over budding young talents Ryan Harrison and Bernard Tomic in straight sets, Del Potro has improved his record to 11-1 at the hard-court tournament.
Big double for big Juan Martin del Potro, losing just 6 games to Harrison in afternoon then just 6 games to Bernard Tomic at night #CitiOpen— Ben Rothenberg (@BenRothenberg) August 2, 2013
The Argentine will face No. 7-seeded Kevin Anderson, who defeated both James Duckworth and Mardy Fish during Thursday's play.
John Isner vs. Marcos Baghdatis
2013 has not been one to remember for Marcos Baghdatis.
Since a second-round victory at the ATP ABN AMRO World Tennis Tournament in Rotterdam, Netherlands, Baghdatis has been bounced out in the first round of every tournament since. That is, until now.
Marcos Baghdatis has ended his losing streak and then some. Absolutely clobbers No2 seed Kei Nishikori 6-1, 6-2. #citiopen— Ben Rothenberg (@BenRothenberg) August 2, 2013
After defeating Lukas Lacko and Kei Nishikori, Baghdatis will face John Isner in the quarterfinals.
Baghdatis will make Isner work for everything in their match.
Isner struggles in the return game, and Baghdatis will make him move, which will result in a series of errors for the American.
However, if Isner can avoid getting fatigued, he could be on his way to the semifinals.
Tommy Haas and the Fountain of Youth
Tommy Haas is proving that he still has game.
Although it took three sets in each of the 35-year-old's previous matches, he is showing that he still has what it takes to possibly make a run at the 2013 U.S. Open.
Friday, he'll be facing 22-year-old Grigor Dimitrov, who has executed with precision throughout the tournament.
Remember: Age is nothing but a number. Hence, look for Haas and Dimitrov to battle throughout.
